Here's some interesting news:
MSNBC - City installs 100-block WiFi 'hot zone'
Wow, free WiFi for an entire city? Boy, the writing sure is on the wall for cheap, ubiquitous broadband!
Of course, if you get a greedy power user using a P2P client such as Kazaa, eDonkey, Emule, etc. they can suck all the bandwidth. Not that I ever do that. ; )
Perhaps they are implementing some sort of traffic management/QoS to prevent bandwidth hogs?
